In these days, when men are trying to go to the moon, people should not think that Kṛṣṇa consciousness is concerned with something old-fashioned. When the world is progressing to reach the moon, we are chanting Hare Kṛṣṇa. But people should not misunderstand and assume that we are lagging behind modern scientific advancement. We have already passed all scientific advancement. In Bhagavad-gītā it is said that man's attempt to reach higher planets is not new. Newspaper headlines read, "Man's First Steps on the Moon," but the reporters do not know that millions and millions of men went there and came back. This is not the first time. This is an ancient practice. In Bhagavad-gītā (8.16) it is clearly stated, abrahma-bhuvanāl lokāḥ punar āvartino 'rjuna: "My dear Arjuna, even if you go to the highest planetary system, which is called Brahmaloka, you will have to come back." Therefore, interplanetary travel is not new. It is known to the Kṛṣṇa conscious devotees.
Since we are Kṛṣṇa conscious, we take what Kṛṣṇa says to be the Absolute Truth. According to Vedic literature, there are many planetary systems. The planetary system in which we are living is called Bhūrloka. Above this planetary system is Bhuvarloka. Above that is Svarloka (the moon belongs to the Svarloka planetary system). Above Svarloka is Maharloka; above that is Janaloka; and above that is Satyaloka. Similarly, there are lower planetary systems. Thus there are fourteen statuses of planetary systems within this universe, and the sun is the chief planet. The sun is described in the Brahma-saṁhitā (5.52):
- yac-cakṣur eṣa savitā sakala-grahāṇāṁ
- rājā samasta-sura-mūrtir aśeṣa-tejāḥ
- yasyājñayā bhramati saṁbhṛta-kāla-cakro
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
"I worship Govinda (Kṛṣṇa), the primeval Lord, by whose order the sun assumes immense power and heat and traverses its orbit. The sun, which is the chief among all planetary systems, is the eye of the Supreme Lord." Actually, without the sun we cannot see. We may be very proud of our eyes, but we cannot even see our next-door neighbor. People challenge, "Can you show me God?" But what can they see? What is the value of their eyes? God is not cheap. We cannot see anything, not to speak of God, without sunshine. Without sunlight we are blind. At night, we cannot see anything, and therefore we use electricity because the sun is not present.
